ISB ~ Revelation 14 v4

they are chaste:Literally, “they are virgins.” This probably has two levels of meaning. (1) The assembly is made up of celibate men whose bodies have never been given to women. (2) The assembly is made up of holy men whose souls have not been defiled by the impurities of the harlot city (17:1-6; 18:3) (CCC 1618-19).

• “The Lamb walks the way of virginity. Follow him there, you virgins, for on this count you follow him wherever he goes. … The masses of the faithful, unable to follow the Lamb to this blessing, will rejoice with you; but they will not be able to sing that new song which is for you alone” (St. Augustine, On Holy Virginity 29).
